I finished a drive and dumped a few gallons of unused coal tar sealer in the grass well away from the house and the driveway. The property owner said it wouldnt hurt to dump it there but we didnt consider the neighborhood cats. And it appears a cat walked through the sealer and climbed onto his car hood. The sealer had been on the vehicle for several days before the property owner realized what happened. Any ideas what might work to soften the sealer up so it can be removed from the car hood. Right now we have a pieces of cotton t-shirt material soaked with turtle wax brand bug"n"tar remover laying over the tracks.
